Nervous System

It very much depends on what you mean by 'read'. Brain waves are captured routinely every day, in various medical and research settings around the world. But if by read you mean can a computer translate or interpret your thoughts so they can be accurately revealed to others, the answer is no, not yet. Emotional states can be generally determined by brain activity, but specific thoughts, mental images or actual unspoken language cannot be 'read' by any computers known. But that may be changing. The brain is sometimes considered out 'last frontier', the last monumental thing about which we know practically nothing. But we are learning more and more every day.

Vestibular schwannoma, also known as acoustic neuroma, is a non-cancerous tumor that develops on the nerve responsible for balance and hearing, called the vestibulocochlear nerve. Symptoms can include hearing loss, tinnitus, imbalance, and in severe cases, facial weakness or numbness. Treatment options may include observation, radiation therapy, or surgical removal of the tumor.

Sympathetic nervous system, triggering the "fight or flight" response to help you respond to the threat. This activation leads to increased heart rate, dilated pupils, and heightened awareness to prepare the body to defend itself or escape the danger.

The release of 'neurotransmitter substances' from an axon's perifery which traverse the synaptic cleft - the space between axon and adjoining dendrite - to both affect and effect the adjoining dendritic "perifery" which then re-initiates signal propagation to the next bunch of exonic nerve "endings".

Basically everything will reach an equilibrium, and homogeneous mixture of "everything", if given enough time. Living systems stay living by maintain a specific range of disequilibrium within its components (for the most part). The 2nd Law of thermodynamics states basically that temperature, pressure, and chemical potential goes into equilibrium given enough time. this equilibrium is entropy, when things become compartmentalized (ordered) its always do to living systems.

Sympathetic stimulation results in renin secretion by the kidneys and causes a relaxation of the bladder. Accompanied by a constriction of the bladder sphincter, sympathetic stimulation tends to decrease urination and promote fluid retention.

Damage is due to nerve root compression. Only a very small compression will interrupt blood flow to a nerve cell, resulting in numbness or tingling. Pain occurs when the damaged nerve is irritated.

Reflexes are actually carried to the brain through sensory neurons that send signals to the spinal cord. The spinal cord processes the incoming sensory information and coordinates a quick response, sometimes without direct involvement of the brain. This allows for rapid reflex actions to occur without the need for conscious thought.

Neurons are the main cells that perform the function of transmitting electrical and chemical signals in the nervous system. They are specialized for communicating signals between different parts of the body.

As you age, your sense of smell can become weaker, making it harder to detect and distinguish between different odors. This decrease in sensitivity is due to changes in the olfactory system and a reduction in the number of olfactory receptors in the nose. Older adults may also experience a decline in their ability to identify and remember smells accurately.

The lacrimal gland is located superior and lateral to the eye within the orbit. It is situated near the outer canthus of the eye and is responsible for producing tears that lubricate and protect the eye.

Tears are produced by the lacrimal gland and the accessory lacrimal glands and cover the cornea. Tears then drain out the punctum in the medial eyelids, flow down the canaliculi into the lacrimal sac. They then drain down the nasolacrimal duct into the nose at the inferior meatus (under the inferior turbinate).
from the lacrimal galnd to the lacrimal canals (lacrimal puncta canaliculi) to the lacrimal sace, then the nasolacrimal duct and finally the nasal cavity

The parasympathetic nervous system decreases blood pressure by promoting relaxation and decreasing heart rate. It counters the effects of the sympathetic nervous system, which increases blood pressure.

The fiber that transmits impulses to the central nervous system is called an afferent or sensory fiber. These fibers carry sensory information from receptors in the body to the brain and spinal cord, allowing for the perception of different sensations like touch, temperature, and pain.

Chemical signaling between cells is advantageous because it allows for communication between distant cells and tissues. This form of signaling is also slower and more sustained than nervous signaling, making it suitable for coordinating long-term processes such as growth and development. Additionally, chemical signals can be released systemically throughout the body to affect multiple cell types simultaneously.

Yes, peripheral nerves connect the spinal cord to the limbs and other parts of the body. These nerves carry messages between the brain and the rest of the body, allowing for movement and sensation.

Nerves do not fire at varying intensities; for example, neurons won't fire at a stronger intensity if you're hit with a baseball in comparison to a marble. The difference between the two stimuli is the number of firing neurons. After being hit with a baseball, the affected neurons will fire more frequently than if hit with a marble.

Nothing stays the same, right? The answer is, of course.

The long branch of a nerve cell is called an axon. It transmits electrical signals away from the cell body to communicate with other neurons or muscles. The axon is covered in myelin, which helps to speed up signal transmission.

Yes, rods contain the photopigment rhodopsin which is sensitive to low light levels. Rhodopsin is composed of a protein called opsin and a light-sensitive molecule called retinal. When rhodopsin is exposed to light, it undergoes a chemical reaction that leads to the generation of electrical signals in the rods, initiating the visual process.

Schwann cells enhance the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system by forming a myelin sheath around the axon. This myelin sheath insulates the axon, allowing for faster conduction of the action potential through a process known as saltatory conduction.

Hyporeflexia is typically caused by disorders of the peripheral nervous system, specifically affecting the spinal cord and peripheral nerves. These disorders can include conditions like peripheral neuropathy, Guillain-Barré syndrome, or nerve compression.

The lacrimal glands produce tears that help to lubricate the eye, keep it moist, and wash away debris or foreign particles. Tears also contain enzymes and antibodies that help to protect the eye from infections. Overall, the function of the lacrimal glands is essential in maintaining the health and function of the eye.
